<p>A temperature conditioning system has a temperature conditioning apparatus (12) such as a heating apparatus (13, 14) and/or cooling apparatus (21, 22), an air treatment for cleaning apparatus (30) and a fan (23) for moving air through the temperature conditioning apparatus and air treatment apparatus to supply the conditioned air to a space (10) in which the temperature is controlled by a space thermostat (11) connected to control the heating and cooling apparatuses. The space thermostat (11) has a switch (32) connected through a fan cycler (35) to provide for cycling the fan independent of the operation of the heating and/or cooling apparatus to periodically move air through the air treatment apparatus and throughout the space to insure that the air is periodically treated and moved throughout the space to prevent stagnation when there is no call for operation of the heating and/or cooling apparatus.</p> |
